Welcome to Southbank International School

We are London's leading International Baccalaureate (IB) School, offering a different approach to academic excellence for children aged 2*-18

At our Central London campuses in Hampstead, Kensington and Westminster, we nurture talent, celebrate individuality and develop curious, inquisitive and constantly challenging minds. Our students consistently achieve outstanding results and first-choice university offers.

The International Baccalaureate (IB) program is enjoyed by both international learners and those who have not previously studied the IB, including children moving over from private primary or secondary schools. The IB aims to do more than other curricula. It builds students critical thinking skills, nurtures their curiosity and their ability to solve complex problems.

Through a commitment to academic excellence and a uniquely liberal ethos, the IB also develops students with an inner belief in themselves. Southbank students have an openness to the outside world and a desire to give back to communities on a local, national and global level.

100% Pass Rate For The IB Diploma

We are delighted to share the outstanding achievements of our students in the IBDP results.

Out of the 86 diploma students who participated, one of our biggest cohorts to date, 100% successfully passed and 86% scored higher than the world average (30.32), our Southbank average is 36. This is a remarkable feat and something we are extremely proud of.

*A score of 34-37 in the IB is roughly equivalent to AAA at A-Level. These comparisons are approximations and can vary by subject and university. 

Congratualtions to our Class of 2024 for achieving such fantastic IB Diploma results which reflect their phenomenal academic performance.
